Tess Hermes

Tess is a high-energy improv trainer and communication coach with 12+ years of experience helping professionals—from ambitious sales teams to seasoned executives—show up sharper, faster, and more human in the moments that matter most. Her secret weapon? Improv. Not the stage kind with spotlights and punchlines, but the kind that builds real-world agility, confidence, and connection.

A long time improv teacher at The Hideout Theare and Fallout Theater, Tess boasts a background that bridges performance and business. She’s especially passionate about helping leaders elevate their presence and sharpen their presentation skills—whether they’re addressing a boardroom, a client, or a company-wide all-hands.

Tess believes improv isn’t about being funny—it’s about being present, listening deeply, and responding with purpose. She shares her expertise through her improv training consultancy, yes&sell. Her sessions are engaging, energizing, and built to create meaningful, lasting change.

If your team is ready to break out of old patterns and elevate how they lead, sell, and communicate—Tess is ready to help make it happen.

“Tess’s uniquely creative and engaging approach made sales fun again. I thoroughly enjoyed my time with her and would suggest Tess to anyone with either a creative background or seasoned sales professionals jaded from the ‘Always Be Closing’ grind who want to expand their repertoire and view sales from a fresh perspective.”
